The genus Agastache, commonly known as Hyssop or Hummingbird Mint, encompasses aromatic perennials cherished for their long bloom season and upright floral spikes. A popular modern introduction is the hybrid cultivar, Agastache ‘Queen Nectarine’. This variety was selected for its improved vigor and robust, full growth habit, making it a highly desirable garden plant. As a member of the MEANT TO BEE® Collection, this perennial is recognized for its reliable performance in the landscape.
Distinctive Features and Fragrance Profile
The visual appeal of ‘Queen Nectarine’ is characterized by a distinctive two-toned floral display that begins in mid-summer and continues well into the fall. The individual flowers are soft peach to apricot in color, forming dense, upright spikes that emerge from prominent mauve or rosy-pink calyxes. These colorful calyxes are a unique attribute, as they retain their vibrant hue even after the small tubular flowers fade, extending the plant’s visual interest for months.
This hybrid develops an upright, mounding habit, typically reaching a mature height of 30 to 36 inches with a similar spread. The medium green foliage possesses a spicy, minty, or anise-like aroma, characteristic of the Hummingbird Mint group. This scent is released when the leaves are brushed or crushed, and it makes the plant unappealing to deer and rabbits.
Essential Growing Conditions
For ‘Queen Nectarine’ to achieve its full potential and robust flowering, it requires a location that provides full sun, meaning a minimum of six hours of direct sunlight daily. Inadequate light exposure will result in fewer blooms and a weaker, less upright structure. The primary requirement for long-term health is exceptionally well-draining soil, as the plant is adapted to thrive in dry, hot conditions.
The root system is intolerant of prolonged wet or soggy conditions, especially during winter, which can quickly lead to crown or root rot. While the plant tolerates average to light soil and performs well in poor or rocky conditions, heavy clay that retains moisture is detrimental. Gardeners with heavy soil should amend the area with coarse sand or gravel to improve drainage before planting. ‘Queen Nectarine’ is a cold-hardy perennial, reliably growing across USDA Hardiness Zones 5 through 9.
Seasonal Care and Longevity
Once established, the plant has low watering needs and exhibits drought tolerance. Regular watering is necessary during the first season to encourage establishment, but afterward, the soil should dry out moderately between waterings. Overly rich or fertile soil is discouraged because it can cause stems to become weak and floppy, so supplemental fertilizer is generally not required.
To ensure a continuous display of blooms from summer into fall, spent flower spikes should be deadheaded to encourage a new flush of flowers. In colder climates, dormant stems should be left standing throughout the winter to protect the crown from cold and excessive moisture. The old foliage and stems can be cut back to the ground in late winter or early spring, just before new growth begins. As a hybrid, ‘Queen Nectarine’ is typically propagated vegetatively, such as through stem cuttings or division.
Landscape Applications and Pollinator Attraction
The vibrant flowers and upright habit make ‘Queen Nectarine’ a versatile choice for many garden styles, including cottage gardens, mixed perennial borders, and container plantings. Its tolerance for lean, dry conditions makes it an excellent candidate for xeriscaping or rock gardens where many other perennials struggle. When planted in masses, the collective effect of the peach and pink spikes creates a striking visual impact that can define the middle or back of a garden bed.
This Agastache strongly attracts beneficial insects and birds. The nectar-rich, tubular flowers are a favorite of hummingbirds, which are drawn to the height and color of the spikes throughout the blooming season. Bees and butterflies also frequent the plant, supporting local biodiversity and making it a productive addition to any wildlife garden. The sturdy stems also offer value as a cut flower, bringing the unique color palette indoors.
